Especially Pioneer, Kenwood, Sony, etc.. TDA7240 is used in popular brands like car stereo integrated amplifier powered with a simple amp 12 volt single supply integrated circuit with a power output of 20 watts and two prompts, stereo can use the circuit used. Integrating the output short circuit, over temperature protection there.
TDA7240 The TDA7240A is a 20W bridge audio amplifier IC designed specially for car radio applications. Thanks to the low external part count and compact Heptawatt 7-pin power package the TDA7240A occupies little space on the printed circuit board.

TDA 7240 amplifier circuit Eagle PCB and schema files have been prepared by the great advantages of working with a standard 12-volt car you can use your PC powersupply voltage can work with most 12 volt transformer 50 watt transformer can use the outfitter had in Passive elements of a speaker cabinet are very few good writers with a nice audio data circuit placed into a wooden box with metal or aluminum box would be my suggestion.

Besonders Pioneer, Kenwood, Sony usw. TDA7240 wird in bekannten Marken verwendet, z. B. in integrierten Auto-Stereo-Verstärkern, die mit einer einfachen integrierten 12-Volt-Schaltung mit einer Ausgangsleistung von 20 Watt und zwei Eingabeaufforderungen betrieben werden. Stereo kann die verwendete Schaltung verwenden. Integration des Ausgangskurzschlusses, dort Übertemperaturschutz.
